The Beatles - I mean it's got to be in it surely? It's like the blue print for pop songs
Led Zeppelin - Now this is Rock and Roll
The other 3 are just all up for grabs
Pink Floyd
The Clash
The Who
Rolling Stones
Deep Purple
Queen
Oasis shouldn't be in it, it's too new (even thou is more than a decade), but it's music isn't ground breaking. Nor does muse or anything after 1980, i am not saying that are not good but they wouldn't be here if not for bands that came before them. Which to me had to be a step above other bands to break new grounds.
